A refinement of the highly successful Port-O-Sonic, the Super-Sonic is the first manifold ever designed to take full advantage of the Holley 4500 carb. From the mounting pad to the giant plenum through the big runners, the Super-Sonic is designed to produce the power. The secret is the use 4 paravanes at the bottom of the plenum to direct the gas/air mixture through the runners in an even distribution pattern with a minimum turbulence factor. Recommended carb is Holley Part# R-7320AAA. Max Torque begins at 7,000 RPM Max HP continues through 9,000 RPM range.
